I still think it is probably related to USB3:
- It works with 2 other PCs with exactly the same OS level, but USB2 (same 
scanner)
- This PC used to be USB2, and the scanner worked. A year ago I changed the 
motherboard, this one is USB3-only
- I also get the exact same failure with an older LIDE 100

This is the only USB3-only computer I have, though. And no way to force it to 
behave like USB2. Some motherboard have the option in their BIOS, not this one 
:(
